Issue: Downlink command doesn’t Ack since the last Release
Setup: Firmware in last release 1.1.0062 R202
Older version firmware :
Updated Firmware
LoRa® Server: OFF
Details:
I paste here the log that concerne the problem on R202 revision

This seems to be a bug. I am trying to solve it

Ok, thanks for the reply. I’ll continue my work with the previous firmware version.
Note that loraserver 3.x specified a “gateway/+/event/exec” which is the result of the execution of a given command.

Configuration MQTT bridge
Packet forwarder conf
I use the ProtoBuf definition for the gateway messages from Chirpstack
I code in GoLang and use the standard Golang protoBuf Marshaller
The build-in loraserver is stopped

Why the MQTT Broker Address is localhost (127.0.0.1)? Did you use the MQTT Broker inside the gateway to communicate with Chripstack?

I use the following architecture :
Our application catches the Lora Message from the gateway, stores messages and sent it later to another Main Gateway over Lora.
Note that , in order to enable the gateway to gateway communication, we use a small hack (as specified in pure Lora Layer), and the gateway sent the message with polarization inversion=false .
